Given:

Sphere and cylinder have same radius and height.

Volume of the cylinder = 48 cm³

To find:

The volume of the sphere.

Solution:

Radius and height of cylinder are equal.

⇒ r = h

Volume of cylinder:

V=\pi r^2h

Substitute the given values.

48=\pi r^2r   (since r = h)

48=\pi r^3

48=3.14 \times r^3

Divide by 3.14 on both sides.

$\frac{48}{3.14} =\frac{3.14\times r^3}{3.14}

$15.28=r^3

Taking cube root on both sides, we get

2.48 = r

The radius of the cylinder is 2.48 cm.

Sphere and cylinder have same radius and height.

Volume of sphere:

$V=\frac{4}{3} \pi r^3

$V=\frac{4}{3} \times 3.14 \times (2.48)^3

V=63.85

The volume of the sphere is 63.85 cm³.

Suppose that you are provided with the following data for your country for a particular month: 200 million people are working, 2
lisov135 [29]

Answer:

Unemployement\,\,rate=23%

Step-by-step explanation:

To find the unemployment rate we have the next expression:

Unemplyment\,\,rate=\frac{Unemployment\,\,people}{Total\,\, labor\,\, force}\cdot 100

We have the next data:

200 million employed

20 million unemployed

40 million umemployed are not  looking for a job

Then the total labor force will be the employed and the unemployed population then de have 260 million

Unemployement\,\,rate=\frac{60million}{260million}\cdot 100

Unemployement\,\,rate=\frac{6}{26}\cdot 100

Unemployement\,\,rate=0.23\cdot 100

Unemployement\,\,rate=23%

There are 64 singers in the choir.The tenors and sopranos are in separate rows.There are 8 singers in each row.There are 4 rows
stealth61 [152]
4 rows because 4 times 8 equals 32, so then there are only 32 singers left. 64-32=32, and once again 4 times 8 equals 32.
